TEMPORARY BINDER.

Be it known that l, CHnsLnr DOM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of hio, have invented cert-ain new and useful Improvements in Temporary Binders, of which the following is a specification.

My invention relates to a temporary binder for loose sheets, in which a follower member is movable upon a pair of impaling posts secured and projected from a base member, the posts passing through perforations in the sheets, the sheets being clamped between the follower and base members. The disclosure herein, however, primarily appertains to the follower' member and the parts thereof and their correlation to and with the posts.

An object therefore is to provide the follower member with a swingingly mounted plate apertured to receive a post therethrough. rlhe position of the plate governing the free or restricted movement of the follower on the post, the plate being arranged So that when it is in a horizontal position its aperture will be concentric with the post and when in an angular position eccentric thereto, and bind upon the post to prevent upward movement of the follower. rlhe follower' is provided with a slide member having inclined ianges adapted to engage each of said post binding plates upon opposite sides of the post to swing the same to its horizontal post releasing` position against the tension of spring which urges the plate to its angular position when the slide is removed.

The features of my invention will be more fully set forth in the description of the accompanying drawings, illustrating a preferred embodiment thereof, forming a part of this specification, in which Figure l is a central section through the follower or movable cover member of a loose sheet binder, with the base member and its posts shown in elevation. Fig. 2 is an enlarged sectional view of a portion of the follower casing and post locking member in a normal released position. Fig. 3 is a similar view showing the locking member in its Fig. 4 is a section on line m, F ig. l. Fig. 5 is a section on line e, e, Fig. l.

l represents a base plate, provided with the posts 2, 3, which may be designated as Specication of Letters Patent. Ptenfgd luar 24:, 1914:. Application filed December 30, 1912.

stationary elements of the binder, and 4 represents a follower or movable member through which the posts project, and movable toward and from the base plate or member l to clamp sheets of paper engaging the posts between the members l and l. The follower Ll is stamped and formed from a sheet of metal into a rectangular or oblong tube or shell and is utilized as a casing or housing for the locking elements. The follower and base are usually bound within bool; binder material hingedly carrying a cover for inclosing the sheets. The follower shell or tube is provided with the caps 5, having' tangs 6 adapted to be frictionally pressed into notches formed in the ends of the follower, uniting the same and forming substantially an integral element. The caps may be secured in various ways, while the form shown is the most preferable, as no auxiliary fastening means other than those formed integral with the members are employed. This provides a neat finish for the ends of the follower with no sharp corners and produces a more satisfactory finish when the follower is bound or covered. This type of binder may be provided with any number of impaling posts, dependent upon its size and particular usage, although two posts comply to a standard meeting the general demands of the trade, and, therefore, such type will be principally referred to in this description. The follower is adapted to be clamped to each post and the locking instrumentalites designed to automatically bind with the post or posts resisting an upward or releasing movement of the follower upon the posts, but. free to move in an opposing direction to clamp the sheets; means are, however, provided to position the locking instrmnentalities to render them inactive so that the follower can be freely moved upon the posts in any direction. Each post locking member comprises a plate 7 provided with an orifice through which a post projects, the edges of the orifice binding with the post when the plate is angularly disposed, and released therefrom when moved to a horizontal transverse position, or at right angles with the longitudinal axis of the posts. The plate is provided upon two opposing edges with the depending ears 8, each having a tang 9, adapted to seat within an orifice 10 of slightly larger area formed in the shell or follower a, which together with the shoulders adjacent to the tangs serve as a hinge for the plate 7, and retain the same in its operative position within the follower. This form of connection has an advantage in that no auxiliary hinge or pivot elements are required, reducing the number of parts and materially cheapening the cost of manufacture and having the further advantage in assemblage, rendering convenient insert-ion within an integral shell form of follower.

It will be observed from Fig. 1 that the lockingmembers are Qppositely disposed relative to each other and this provision is made to enable the same to be simultaneously operated or moved to an inactive non-post engaging position by a reciprocating member slidably mounted within the follower. The reciprocating member or slide comprises a U-shaped plate 11, having oblong slots 12 formed in its base, through which the posts pass, one for each post and which permit its requisite movement for loclr plate control. The limbs or flanges 18 of the slide member have a portion thereof notched or cut away to provide the inclined or angular surfaces 14, which engage beneath the lock plate 7, to move the lock member or members from an angular to a horizontal plane or position of absolute post release or restore the same to an active position. rlhe slide member 11 is retained in its position within the follower by a yoke strap 15, which may be formed integral therewith or otherwise, and 16 represents a thumb or button screw projected through an oblong slot 17, in the upper wall of the shell or follower 4, and engaged with the slide member 11 to move the same to the right or left and which provides an exterior hand hold for slide manipulation.

1S represents a spring fixed to the shell or follower l, preferably interior thereof, engaging with a lock member 7 to maintain the same under tension in an angular' position and thereby insure a bind of the loci;- ing member with its post in an upward or releasing movement of the follower and to resist such. A spring 1S is provided for each locking plate.

lt is obvious that a single inclined or cam surface could be provided on each of the slides, each engaging its respective lock plate at one side of a post, but this might have a distorting tendency and would not o'er the positive results as are produced by a plural member mounted on the follower movable tov different transverse planes relative to the circumferential longitudinal surface of thepost to lock the follower against movement on the post, and permit movement thereof toward the base member, said member comprising a plane plate apertured to receive a post therethrough having ears projecting from opposing edges terminating in tangs which loosely socket into apertures in the follower whereby said plate is hingedly mounted.

2. A loose sheet binder of the nature disclosed, combining the base member, an impaling post projected therefrom, a follower apertured to movably receive therethrough said post, a lock member swingingly mounted on the follower encircling said post and normally occupying, under tension, a plane so as to bind with the post and resist movement thereon in one direction, and a member slidably mounted upon said follower having a longitudinal slot to receive said post therethrough and provided with inclined elements arranged to engage beneath and move said lock member to a post releasing position.

3. A loose sheet binder of the nature disclosed combining a base member, an impaling post projected therefrom, a tubular follower apertured to movably receive said post therethrough, a thin rectangular plate apertured to receive said post having projections formed on opposing edges loosely engaged within said follower for swingingly mounting said plate, a slide member movable within said follower longitudinally slotted to receive said post, and provided with angled elements arranged to engage said plate to positively swing the same in one direction and a spring for urging said plate in a direction reverse to the positive movement of said slide.

In testimony whereof, I have hereunto set my hand.
